thanks Justin, that'* exactly what it was! I think we may have found the problem; both keys have same resistance but the new key is flat across the top instead of having a slight bump as the original key has. The new key looked tarnished and under a magnifying glass I could see some very small 'shiny' places. It looks as if it wasn't making good contact. My wife is using the original key so if the problem stops.....
